Think about it this way
3 `; k0 s+ A. B2 V2 ^% ~5.39.217.77:88981) if the 100 bucks is not a fake one, the store owner will gain $3 ($21-$18)
( E& j- a8 W, i$ w% a5.39.217.77:88982) Now, the owner discovered that the 100 bucks is fake. You can think this as a lost of $100. therefore the overall gain is $3-$100 = -$97
